JOHN VAUDREU'IL, MILWAUKEE, WISCONSIN.

DISHWASHER.

Application filed February 15, 1922. Serial No. 586,627.

To all whom it may concern:

Be it known that I, JOHN VAUDREUIL, a citizen of the United States, anda resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented new and useful Improvements in Dishwashers, ofwhich the followin is a description, reference being had to t eaccompanying drawings, which are a part of this specification.

This invention relates to dish-washing machines and more particularlytothe casin or housing portion thereof.

he object of the invention is to provide a casing having one or morerevolving doors afiording access to the interior of the casing and soassociated with the stationary parts of the casingasto prevent theleakage of the washing fluid from the casing.

With the above and other objects in view the invention consists in thedevice hereinafter described and all equivalents.

In the drawings: Fi 1 is an elevation view of a device embo ying theinvention; Fi 2 is a section taken on the line 22 of%ig. 1; Fig. 3 is aplan view; Fig. 4 is a section taken on the line 4-4 of Fig. 2; Fi 5 isa vertical sectional view of a modifi form of device; Fig. 6 is a planview of the device shown in Fig. 5; Fig. 7 is a section taken on theline 7-7 of Fig. 5.

Referrin to Figs. 1 to 4, inclusive, the numeral 8 esignates the baseportion of the casin provided with cylindrical portions 9 an 10 andannular flanges 11 and 12. A fixed inner casin section 13 has its loweredge riveted or ot erwise suitably secured to the portion 9 and extendsabout half-way round said portion 9 and preferably has a hemisphericalportion 14 emerging into a semicylindrical portion 15. A fixed outercasing section 16 has its lower'edge riveted or otherwise suitablysecured to the portion 10 and extends about half-way round said portion9 and preferably has a hemispherical portion 17 merging into asemicylindrical portion 18. The portion 9 being of less diameter thanthe portion 10, the inner section 13 is spaced from the outer section 16about the width of the flange 12. The sections 13 and 16 have bosses 19and 20, respectivel adjacent pivot openings 21 and 22. ith thisconstruction su stantially half of the casing above the base is open.

' A movable casing section or door 23, of

"a shape and size to move within the space between the sections 13 and16 and to cover the half-open casing and overlap the inner edges of saidsections as at 24, has its lower edge slightly above the flange 12 andis pivotally mounted at its top upon a pivot pin 25 passing through theopenings 21 and 22, said pin having washers 26 mounted thereon andspacing the fixed and movable sections apart. When the door is turned,as by a handle 27, to its closed portion, shown in Figs. 2 and 3, thewater from the spraying device 28 is confined within the casing and suchwater as gets in between the sections of the casing or upon the flange12 is drained back into the base by providing openings 29 in the casingsection 13 and openings 30 in a semicylindrical guide band 31 secured tothe portion 10.

The base portion 8 has apertured bosses 32 secured thereto receiving thele s 33 of rods 34 which form supports for t e dishcarrying basket 35which in the present instance is disposed above the spraying or washingdevice 28. When the door 23 is turned to open position, as shown in Fig.4, the basket 35 may be readily removed from or replaced in the machine.

Referring to Figs. 5 to 7, inclusive, this construction has a baseportion'36, similar to the base 8, and inner and outer fixed casingsections 37 and 38, respectively, mounted on and secured to the baseportion in the same manner as the sections 13 and 16 are connected tothe base 8. These sections 37 and 38 are thus spaced apart and they areof spheroidally curved formation and formed to provide diametricallydisposed openings 39, whereby a dish-carrying basket may be introducedinto the. interior through one of these openin s and removed through theother opening, t e rods 40, similar to the rods 34 and similarly mountedon the base portion, forming a support for the basket. Arcuate guidebands 41 are secured to the. base portion in the openings 39. Drainopenings 42 are provided in sand bands and drain openings 43 areprovided in the inner casing 37. v

A movable casing section or door 44, of a shape and size to move withinthe space hetween the sections 37 and 38, covers the flange 47 of thebase portion. The fixed casing sections and the door have alinedopenings in their tops receivin a pivot bolt 48 and washers 49 space thecar from the fixed sections at this point. When the door 44 is turned,as by a handle 50, to closed position, shown in Figs. 5 and 6, the waterfrom the Washing device is con'fined within the casing, and such wateras gets in between the sections of the casing or upon the flange 47 isdrained back into the base by passage through the drain openings 42 or48. When the door is turned to open position, as shown in Fig. 7, thebasket may be removed or replaced from either side of the machine orintroduced through one side and taken out at the other side.

In each instance I prefer to mount the casing upon a tripod 51 and thewater supply pipe 52 for the spraying device comes in below the base tothe central part thereof and a drain pipe 53 also connects with anopening 54 in the base portion of the casing. As the spraying devicedoes not constitute a part of the present invention, it has not beendescribed in detail. The casing, however, has been designedwithparticular regard for those types of spraying devices which directthe washing water or fluid upwardly upon the dishes in the basket.

It will be noted that in each instance the casing includes a baseportion and a domeshaped upper portion formed or fixed casing sectionsand a movable door section, and that the fixed and movable sections ofthe casing overlap to prevent the passage of water from the casing whenthe door section is closed.

wearer What I claim as my invention is:

I. In a dish-washing machine, the combination of a fixed oasin providedwith an opening, and a movab e door completing said casing and pivotallyconnected to the top thereof, a part of the casing having a double wallreceiving the door when said door is moved to open position, the edgesof the door projecting into the space between said double walls when inclosed position.

2. In a dish-washing machine, an enclosing casing comprising a base andan upper structure forming the top and side portions of the casing, saidupper structure comprising fixed casing sections spaced apart, and amovable casing section forming a door, said movable section beingpivotally mounted at its to between the fixed sections.

3. n a dish-washing machine, an enclosing casing including double wallsat the side and top of the casing and an annular flange between saidWalls, and a door completing the casing and pivotally connected at thetop between said walls, said door passing between said double walls whenmoved to open position and having its edges projecting into the spacebetween said walls when in closed position.

4. In a dish-washing machine, an enclosing casing comprising a baseportion and a dome-shaped structure mounted on said base portion, saiddome-shaped structure including fixed casing sections, and a slidingdoor section pivoted to the top of said fixed sections and movablebetween them to establish a passage through said casing.

In testimony whereof I afiix my signature.
